First Claim
1. An complex electric power system unlimited in size, but with a finite number of generation units, grid elements, consumers, national or regional districts, and distribution networks, enabling each consumer to receive electricity and real time prices simultaneously, which system is characterized by the following additional equipments installed for efficient control end secure supply of electricity:
- —
a Bidder, installed at the control room of each generation unit, enabling to submit to the system operator bids for suggested power and prices, and also information for contracted power and prices, for each hour in a continuous rolled horizon;
—
a Scheduler and Price Designator installed at the control board of the system operator by which he determines the dispatched amount of power or ancillary services and the prices, that are to be realized on every generation unit over the next single price period, and by which he notifies the operators of generation units;
—
a Price Announcer installed at the control room of each generation units enabling constant labelling of price to the power generated according to the products dispatched to the unit, and to transmit the labels to the grid nods by which the generation unit is connected;
—
a Price “
Transmuter”
installed at each grid node enabling to determine the surcharges due to possible congestion or network security limitations, to add such charges to the received generation prices and to transmit the result to every neighbour node along with the branch charges added;
—
an Intelligent Electric Meter installed at each grid branch and consumer outlet, consisting of metering device, power controller and means for receiving, recording and forecasting of the price, enabling the consumer to receive power and resulting price simultaneously for automatic control of his demand during every Single Price Period, several seconds or minutes long, into a continuous cyclically repeated process.

Abstract
A method and system is proposed for the physical trading of electricity, which is characterized by continuous Dynamic Advanced Prices formation and propagation over a single price period that is a few seconds long. The Node and Branch price equations are applied to the power flows and to the corresponding costs incurred at measure points, as well as to the system-wide costs allocated equitably by means of a Price Designator, Price Announcers, Price Transmuters and Intelligent Meters and by other devices, all of which function together in a sequential and repetitive process of preliminary bidding, clearing, adjustment and dispatching, followed by price designation, confirmation and conversion in a way that takes into account congestion and security costs and the compensation of involuntary deviations. The method provides a common electricity trade environment that allows every market participant, especially every consumer, to respond adequately to last minute price changes.

10. A Method for the dispatch control of a complex electric power systems by which the real-time dispatching procedures are improved by an automatic process for the cyclically repeated formation and propagation of the dispatch notices based on price for every single price period (several seconds or minutes long), during which the system operator determines the dispatched power and the corresponding price for the coming single price period, then by means of price announcer the operator of the generation unit verifies the received dispatcher'"'"'s task, adjusts the unit governor, and sends the labelled power along with compensation amounts to the grid node where the unit is connected, so that the iterated transmutation of the price for the current single price period occur and the price be made official for the purpose of automatic power control and settlement simultaneously.
